WHO KNEW THE DONALD WAS THIS NICE?

Who knew that Donald Trump was such a friend of the little guy? When the reality television star heard that a waiter and a security guard at his Palm Beach club, Mar-a-Lago, found and returned a diamond-and-platinum bracelet lost by a female member at a recent JayLeno-headlined dinner-dance, Trump was shocked to learn that the lady hadn’t tipped the two honest employees. Especially since the bracelet was worth $2 million, as Trump told another Mar-a-Lago guest, Outlaw Biker mag founder CaseyExton, who repeated the claim at New York’s Zocalo restaurant. So what did The Donald do? He phoned the lucky lady — who tells me the bauble is worth “far less than $2 million” — and shamed her into visiting the club on Sunday and leaving two cash-laden envelopes for the good samaritans. How much cash? “I don’t think that’s anybody’s business —that’s ugly,” the lady, not MarthaStewart, told me yesterday.
